SAMUEL T. HUGHES, OF CANONSBURG, PENNSYLVANIA.

MILL FOR ROLLINGlCAR-WHEELS.

SPECIFICATION forming pari'. of LettersPatent No. 366,109, dated July E, 1887.

Application filed April 5, ISST. Serial No. 233.736. (No moduli) To all whom, it may concern:

Be it known that I, SAMUEL T. HUGHEs, a citizen of the United States, residing at Ganonsburg, in the county ofWashington and State of Pennsylvania, have invented certain new and useful Improvements in Mills for Rolling Gar and other Wheels; andldohereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

My invention has relation to rolling-mills or machinery for rolling ear andother wheels from solid steel'or iron blooms; and it consists in the novel construction, combination, and arrangement of mechanism for feeding the rolls according as the bloom is reduced, and for producing` the required pressure between the car-wheel and the shaping-rolls, in order to effectively break down the bloom of steel or iron, as hereinafter described and claimed.

In the accompanying drawings, Figure l is a front elevation, partly in section, of a rollingmill embodying my improvements. Fig. 2 is a vertical transverse section. Fig. 3 is a horizontal section or plan of the same, and Fig. 4 is a detail view.

The mill comprises two sets of housings, A A' B B', between which are located the rolls and the mechanism for supporting thecarwheel. which is being operated upon, and for intermittently raising and lowering it according to the progress ofthe work.

The rolls G C' are shaped to conform to the contour of the face and rim of the wheel D, being provided with the convex heads c c and the iianges d d, the latter being adjustable, so as` to adapt themselves to the spread of the wheel. The rolls rotate on horizontal axes, and are provided with shafts EE', which are mounted in carriages, riders, or bearing-blocks F F', adjustable in the housings, and having` journaled therein or abutting against the same the ends of vertical adjusting-screws f f', which work in screw-boxes g g', fitted in the housings.

The screws ff' carry beveled pinions h h', which engage with a double-beveled gearwheel, G, loosely mounted on the shaft of the roll and carrying a balance-wheel, G.

G(z is a leverwheel attached to a beveled pinion or toothed wheel, G3, working loosely upon the neck of the roll-shaft, and engaging with the upper and lower pinions, h', of the screws f'.

G is a collar, which is screwed or made fast to the neck of the roll-shaft to retain the leverwheel in gear with the pinions 7i'. Therequisite adjustment of the rolls is effected through the medium of the lever-wheel and the gearing and screws connected therewith.

A2 designates a horizontal beam or brace, having its ends dovetailed and let into the housings A B. In the middle part of said beam or brace is an opening, in which is loosely arranged a box, ce, threaded interiorly for the reception and working of a screw, J having its lower end pointed or beveled to iit the conical recess j in the upper end of the mandrel J', which enters the eye of the car-wheel. The box a is formed witha ratchet-collar, a', with which engages, when necessary, a pawl, f, pivoted upon the beam or brace A2. WVhen the pawl and ratchet are in engagement, the box remainsl stationary, and hence any rotation of the screw-shaft J will cause the latter to'be adjusted vertically; but when the pawl and ratchet are disengaged the shaft J will turn without adjustment.

K is the forming-block upon which the carwheel is mounted. Said block rests upon a horizontal wheel, L, which is beveled and toothed on its under side, and which is iixed upon a vertical shaft, K', having its bearing in a recess, K2, in a pillow-block, K". 0n either side of said pillow-block are arranged beveled toothed wheels M M', having short shafts m m' journaled in the pillow-block and in the housings A B, respectively. These wheels engage with and operate the wheel L, and are themselves engaged and operated by a beveled toothed wheel, U, located back of the pillowblock and mounted on a horizontal shaft, L3, to which power is applied, and which has its bearings in said pillow-block and in a housing, L", as shown. Upon the shafts of the wheels M M'- andl turning therewith are the cam-wheels N N', of cylindrical form through nearly their entire circumference, but having the iiat portions n n out or provided thereon.

These 'wheels constitute an essential. feature of roo my invention.

rIhe operation of the mill is as follows: Thebloom or casting from which the wheel. is to be formed is mounted on the forming-block K.

and the rolls adjusted down to the proper gage, While the wheels N N lie with their liat portions under and facing the wheel L. The mill is now started, and as the wheels N N turn their cylindrical surfaces come in contact with the face of the wheel L and raise the latter, thus producing a surlicient pressure of thecarwheel against the rolls to break down thebloom and render them effectively operative in shaping the wheel. As soon as the car-Wheel has performed a single revolution, and the dat portions of the Wheels N N are again brought below the face of the wheel L, the forming- Ablock K, gear-wheel L, and superposed cartion being continued the castin gis again raised into forcible pressure against the rolls and a second pass produced, and so on until the Wheel is finished. As will be understood, the teeth of the gearing'M M are sufficiently long to permit of the required movement of the former without disengagement.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a mill for rolling car or other solid Wheels, the combination, with the rolls and roll-shafts mounted in suitable housings and adjustable therein, of the forming-block K, toothed wheel L, and mechanism, substantially as described, for rotating said wheel and` forming-block, and for causing the same to intermittently rise and fall during the reducing operation, as set forth.

2. In a mill for rolling car or other Wheels, the combination, with the frame-Work or housings of the mill, of the roll C, shaft E, riders F F', adjusting-screws f f, screw-boxes gg', pinious h h', double gear-Wheel G, and gear- Wheel G?, substantially as described.

3. In a mill for rolling ear or other wheels,

'the combination, with the adjustable Workingrolls,oftheforming-blockK,horizontal toothed wheel L, vertically adjustablel upon its axis, vertical gear-Wheels M M L2, and cam-Wheels N N', substantiallyas and for the purpose described.
